How strong is your willpower? Me, about two weeks. Seriously, though, good Champagne can keep for decades, as long as you store it properly (under ideal cellar conditions, not in the refrigerator, which dries out the cork.) Like a dog, Champagne will soften and lose some of its bubbliness as it ages, so don't expect it to be as zippy as a pup when you finally pop the cork.
